Dataset includes water temperature, salinity, and other parameters of netCDF files of CTD data collected at 105 CTD stations on the Scotian Shelf and in Gulf of Maine in fall 2018. This cruise is U.S. State Department MSR U2018-015 as part of the World Data Service for Oceanography.

Dataset includes water temperature, salinity, and other parameters of netCDF files of CTD data collected at 100 CTD stations on the Scotian Shelf and in Gulf of Maine in fall 2016. This cruise is U.S. State Department MSR U2016-018 as part of the World Data Service for Oceanography.

Dataset consists water temperature, salinity, and other parameters of netCDF files of downcast CTD data collected at 79 CTD stations on the Scotian Shelf and in Gulf of Maine in spring 2024. This cruise is U.S. State Department MSR U2024-007 as part of the World Data Service for Oceanography.

This dataset contains CTD casts and salinity water samples taken from research vessel Endeavor (cruise EN573) from 2016-01-26 to 2016-02-11. A number of moored platforms for the Northwest Tropical Atlantic Station (NTAS) and Meridional Overturning Variability Experiment (MOVE) projects were serviced during the cruise. These data were used to calibrate and validate the mooring data. The CTD salinity data have been quality-controlled and adjusted using the water sample data. The raw CTD data files are already available through the Rolling Deck to Repository (R2R) program under https://doi.org/10.7284/122113. Data are in NetCDF format.

This dataset contains processed and calibrated water temperature and salinity CTD data from 7 cruises performed as part of WOCE and CLIVAR in the subpolar North Atlantic between 1994 and 2002. Data are in TXT format.

Cruise 449/1 by research vessel Oceanus in July 2008 had the objective to service a number of moored platforms for the Northwest Tropical Atlantic Station (NTAS) and Meridional Overturning Variability Experiment (MOVE) projects. To calibrate and validate the mooring data, CTD casts with salinity water samples were collected; these data are reported here. The CTD salinity data have been quality-controlled and adjusted using the water sample data. The raw CTD data files are included in this archive as well and contain other parameters such as oxygen, optical attenuation, and fluorescence, which are not thoroughly calibrated. The data format is NetCDF.

This submission contains salinity-calibrated Conductivity Temperature Depth (CTD) data from the 2018 Ocean Observations Initiative (OOI) Irminger Sea 5 cruise (AR30-03). Data quality control methods have been used to assess performance of the CTD instrument. Resulting high-quality profiles were then used together with salinity bottle data analyzed at sea to create a post-cruise salinity-calibrated CTD product. This submission has been produced as part of an ongoing effort to more fully utilize CTD data collected by OOI Irminger cruises, which have been taking place annually since 2014. The hydrographic data collection facilitated by OOI in the Irminger Sea currently supports science for not only OOI end users, but also international oceanographic research projects, including the Overturning in the Subpolar North Atlantic Program (https://www.o-snap.org/), Atlantic Meridional Overturning Circulation Program (https://usclivar.org/amoc) and BioGeoChemical Array for Real-time Geostrophic Oceanography program (https://biogeochemical- argo.org/index.php). Such programs require a higher-level data product than what OOI provides through its standard data dissemination, and hence a quality controlled, salinity-calibrated data product has been produced. Data are in text formats.

The dataset consists of 81 Underway CTD (UCTD) casts in the region north of Flemish Cap. The UCTD is an un-pumped profiling CTD, manufactured by the Oceanscience Group, that can be deployed from a moving ship. The UCTD measures temperature, conductivity, and pressure at 16 Hz. The pressure and its time derivative (descent rate) were low-pass filtered with a filter cutoff period of 2 s. The temperature and conductivity signals were also filtered, but with the filter cutoff period set to 0.25 s. Alignment of the temperature and conductivity was performed as a function of the instrument descent rate using an empirical relationship. Because of the rapid descent rate of the UCTD (up to 4 dbar/s), the measured temperature was corrected for the effect of viscous heating. The effect of the thermal mass of the conductivity cell was accounted for using the standard correction with the parameters determined as a function of the local instrument descent rate. The processed temperature, conductivity, and pressure were used to compute salinity, potential temperature, and potential density. Finally, the data were averaged into 1 dbar bins.
